Semtech LR2022: 4th-Gen LoRa IP for Custom IoT Chips

The Internet of Things (IoT) landscape is about to get a massive injection of versatility. Semtech, a leading global supplier of high performance analog and mixed signal semiconductors, has officially introduced its highly anticipated fourth generation LoRa Intellectual Property (IP); the LR2022.

Unlike traditional standalone chips, the LR2022 is a foundational “blueprint” designed specifically for silicon vendors and chip designers. By licensing this new IP, manufacturers can now seamlessly integrate world class LoRa connectivity directly into their own custom System on Chip (SoC) designs.

Key Features of the 4th Generation LR2022

Semtech’s 4th generation architecture brings a host of upgrades that address the growing demands of modern IoT networks:

• Ultra Low Power Consumption: LoRa is already famous for its battery saving capabilities, but the LR2022 pushes the envelope further. Optimized silicon design means sensors in the field (like agricultural monitors or smart water meters) can last even longer on a single coin cell battery.
• Reduced Silicon Footprint: The LR2022 is engineered to take up minimal space on a die. This allows chipmakers to pack more features such as AI processing cores, extra memory or environmental sensors into a single, compact SoC.
• Enhanced Performance and Sensitivity: The new architecture delivers robust long range connectivity, ensuring reliable data transmission even in dense urban environments or deep indoors, where radio frequency (RF) interference is high.
• Faster Time to Market: By providing a fully verified and tested IP core, Semtech takes the heavy lifting out of RF design. Silicon vendors can skip years of research and development, rapidly deploying LoRa enabled chips to the market.
